The useful answer is no. A Federal Reserve research note published on August 22, 2025, documents that many publicly traded U.S. nonfinancial firms held more cash by mid-2021, before interest-rate increases began in 2022. It does not measure what those firms later paid in interest, what they paid workers, or whether they cut jobs. A larger cash balance can, in principle, help a business meet bills when borrowing becomes more expensive. That possibility is not the same as proof that financially constrained firms, or the people who worked for them, were protected once rates rose.
This is a historical reading, not a new release about borrowing costs in October 2026. The case covers an early-pandemic window, the first through fourth quarters of 2020, and a late-pandemic window, the first through fourth quarters of 2021. The authors, Elie Singer and Jie Yang, then place those savings next to the approach of tighter policy in 2022. The page was checked against that August 22, 2025 note.
How large the public-firm cash pile became
The note uses quarterly accounting data from S&P Compustat for U.S. public, nonfinancial, non-utility firms with positive total assets. Cash-to-assets is cash divided by total assets. It is not profit, and it is not pay already received by employees.
Figure 1 shows the median ratio—the midpoint firm, not a sum of all corporate cash—staying near 12 percent in the years after the Great Financial Crisis. It then rose to a historic high of over 20 percent in mid-2021. The average, which unusually cash-rich firms can pull up, surpassed 30 percent in 2021. The figure’s recession shading includes February through April 2020.
A labeled hypothetical, not a real firm, uses $100 of assets. Near 12 percent, cash is $12. At just over 20 percent, cash is a little more than $20, a gap of a little more than $8 per $100 of assets. The note’s average above 30 percent would be more than $30 per $100 of assets, but an average is not the midpoint firm.
Constrained firms saved faster, except where the shock hit hardest
The authors define financially constrained firms as companies with restricted access to external funding at fair market borrowing costs: they cannot readily borrow or raise equity on terms offered to stronger firms. Prior research summarized in the note says these firms often keep precautionary cash because outside money may not be available, and that they can also be more sensitive to higher interest rates. That is the stated reason the 2022 hikes matter for this savings study.
A downturn can reverse that motive. Lost sales and closed funding markets create what the note calls immediate liquidity needs, which limit saving. The authors therefore split the pandemic.
Early pandemic, 2020 Q1 through Q4, brought high uncertainty about the shock’s length and macroeconomic damage. On average, the authors find, both more constrained and less constrained firms accelerated cash holdings amid recession fears. Late pandemic, 2021 Q1 through Q4, brought a gradual easing of many pressures and somewhat lower uncertainty. Across the pandemic, more constrained firms accumulated cash faster and held it longer than less constrained firms, and that extra saving was larger than in any other recent period the note examines. Many constrained firms, possibly slow to adjust as conditions improved, still held substantially more cash later in the pandemic.
Inside industries most adversely affected, the pattern flipped. More constrained firms accumulated cash more slowly than less constrained firms in those industries. The authors presume immediate liquidity needs were the reason, and they say the most constrained hard-hit firms could not accumulate cash as the broader sample did. Constraint and saving did not move in a straight line.
A pre-hike balance is not a test of later protection
The note suggests that firms typically more vulnerable to higher interest rates had amassed significant cash buffers immediately before hikes began in 2022, and that cash can cushion borrowing costs. That suggestion joins a pre-hike stock of cash to earlier studies. It does not measure later interest expense, loan spreads, or refinancing. The supplied text does not report the size of the rate move or whether firms spent the cash on interest rather than on suppliers or shareholders.
Workers are further removed. Cash-to-assets is not wages, hours, or a layoff count. A firm can hold more cash in mid-2021 and still cut staffing when financing costs rise. The note never connects the buffer to paychecks. In hard-hit industries, constrained firms built cash more slowly, so the employers under the sharpest operating stress were not the ones shown with the larger cushion.
The sample is public U.S. nonfinancial, non-utility corporations only. It leaves out private U.S. employers and Canadian firms. A U.S. parent’s cash ratio is not a Canadian payroll or a household budget.
What would count as evidence of insulation
The documented facts stop at the balance sheet. Public U.S. firms raised cash ratios in 2020–2021, constrained firms in the broad sample saved faster and longer, and constrained firms in hard-hit industries saved more slowly. The liquidity story is the authors’ presumption. None of this is a result for interest bills or jobs after the hikes.
A protection claim would need later evidence: interest expense and refinancing for these public firms once 2022 tightening was underway; whether the extra cash was actually drawn down as borrowing costs rose; and wages, hours, or employment, especially in hard-hit industries. Private employers and their workers would remain a separate question. Checked on October 21, 2026, the August 22, 2025 note does not contain those outcomes. The buffer shows how some balance sheets looked before tightening. It does not prove who was protected afterward.
